STOP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 404,407, dated June 4, 1889. Application filed September 8, 1888. Serial No. 284,903. (No model.)

To all whom it may concern: Be itknown that I, EDUARD HERZIG, a resident of WVest Hobokcn, Hudson county, New Jersey, have invented certain new and use- 5 ful Improvements in Stop Mechanismv for 1 Looms, of which the following is a specification.

The object of my invention is to provide improved means for stopping the loom when the shuttle-thread breaks or when the shuttle I sticks in the shed.

The invention consists in the details of improvement and the combinations of parts that will be more fully hereinafter set forth.

I 5 Reference is to be had to the accompanying drawings, forming in which Figure 1 is a side elevation, partly broken, of a portion of a loom embodying my improvements. Fig. 2 is an enlarged detail View of part of my improvements. Fig. 3 is a detail side view of the parts shown in Fig. 2. Fig. 4 is a detail top view, and Fig. 5 is a detail side view, of the cam for throwing the driving mechanism out of gear. Fig. 6 is a longitudinal sectional view, on an enlarged scale and partly broken, on the line 0 c, Fig. 1, of a portion of the loom, showing some of my improvements in position. Fig. 7 is a partly- 0 broken detail view of the lever for locking the lever that throws the driving mechanism out of gear. Fig. Sis an enlarged detail View of a portion of my improvements shown in Fig. 1. Fig. 9 is a detail edge View thereof;

part of this specification,

5 and Fig. 10 is a detail view of parts shown in,

Fig. 1, the batten being in the forward position. In the accompanying drawings, the letter A represents the frame of a loom, andB is the batten of said loom. D is the shuttle-race carried by said batten, and E are the heddles of the loom. These parts may be of any approved construction.

F is a bracket that is carried by the batten B. In suitable bearings on this bracket is journaled a shaft a, that is provided at one end with a fork or fly G and at its opposite end with a'crank b. The crank 19 is connected by a rod or link (I with a lever II, that is piv- 5o oted 011 the batten B, as shown in Fig. 1.

e is a spiral spring that surrounds the shaft a. Said spring is secured at one end to said shaft, and its other end presses against the bracket F, so as to turn the shaft a to normally hold the fork Gin the position shown in Fig. 1, and to also hold the lever H depressed,

as in said figure. WVhen the batten swings forward to beatup the weft, the free end of the lever II. will strike a tongue I, that is pivoted on a bracket f, that projects from the frame A.

The tongue I is kept in the elevated position by means of a spring g, and is limited in its upward movement by an adjustable stop or plate 7L2, carried by the bracket f. The plate 7&2 has a slot h through which passes a screw 71., that enters the bracket f, whereby the plate h is made adjustable. By adjusting the stop if up or down the vertical movement of the tongue I may be regulated. When the batten swings forward and the lever II strikes the tongue I, said lever will be raised, thereby turning the shaft ct, through means of the link d and crank 12, so as to move the fork G forward into the position shown in Fig. 10. hen in this position, the fork G is adapted to engage the shuttle-thread, as hereinafter shown. By making the tongue I movable slightly the shock and wear on the lever H that would result by its contact with a stationary abutment are avoided.

J is a fork or open frame that is carried by a vertical rod h. The rod it passes into a pivoted block 2', that is hung on a support j, that is carried by the frame A. The fork G is adapted, when the batten swings forward, to contact with the fork J, or, in other words, the prongs of the fork G are adapted to pass into the spaces between the prongs in the fork J, as in dotted lines in Fig. 6. The upper end of the rod h is guided by a forked rod Z, carried by the support j. The lower end of the rod h is connected to a lever L, that is pivoted at one end upon across-piece m, carried by the frame A, which lever is adapted 5 to be moved laterally by the rod h. The lower end of the rod h and the lever L are moved toward or against the support j by means of a spring n, as in Fig. 6. The free end of the lever I. is adapted to come over I00 one end of a lever M, the opposite end of which lever M is forked and rests upon a rod 0, as in dotted lines in Fig. 1.

N is a rod that passes across the frame A and rests upon the lever M. The rod N is connected to the devices for throwing the driving-gear of the loom out of action. The rod N is notched, as at n in Fig. (3. N passes through a hole 1) in the frame A, its notch a resting on the metal of the frame A at said hole when the loom is in operation; but when the rod N is raised and its notch disengaged from said metal said rod will be drawn to one side and throw the driving mechanism out of gear, as in ordinary looms. The outer end of the lever M is kept upon the rod 0 by a spiral spring q, that is connected at one end to said lever and at its opposite end to the frame A. The lever M is connected by a rod 0' with a lever O, that is pivoted at one end in the frame, and at its opposite end said lever rests upon a cam P, that is carried by a shaft Q, hung in hearings in the frame A and driven by suitable mechanism. The free end of the lever O that contacts with the cam P preferably has a projection, as shown in Fig. 1.

The cam P which I prefer to use is of the construct-ion shown clearly in Fig. 5-that is to say, for a portion of its circumference it is circular, it then has a slightly-raised part .9 for another portion of its circumference, and at the end of said raised part it is provided with a projection or tongue t. Above the free end of the lever L is a stop U, that limits the upward movement of the lever M when the lever L is beneath the stop U. The stop U is high enough above the lever .L to permit the part 3 of the cam 1 to raise the lever M when the lever L is over said lever M; but'said stop U prevents the projection I; on the cam I from raising the lever M when the lever L is above it, so that the outer end of the lever M will be raised by the cam 1 R is a lever that is pivoted to a support 1*, carried by the frame A. The pivot u: of the lever R passes through a vertical slot as in said lever, within which slot is a spiral spring 1 that bears against the pivot w and against the bottom of said slot, which spring acts to keep the lever B depressed, while permitting said lever tohave a slight vertical movement. (See Fig. 7.) The upper end of the lever B is adapted to be engaged by the batten B to move the lower end of said lever outward. The lower end of the lever R is adapted to come above the free end of a lever M that is constructed and operated similarly to the lever M. The leverM is connected by a rod 0' with a lever that is acted upon bya cam P similar to the cam I carried by the shaft Q. The free end of the leverM is adapted to engage the rod N in manner similar to the lever M. The lever O is hung in the frame A similarly to the lever O. The cams l and P are placed upon the shaft Q with their projections facing in opposite directions, as in Fig. l.

The rod' My improvements operate as follows: Suppose the above-described parts to be at the right of the loom and at the right of the cloth being made upon said loom. The shuttle now thrown from the left to the right and comes to rest in the box I) at the end of the batten B. In its passage across the batten the shuttle lays a thread in the shed in the usual way, said thread being laid in line with and between the forks G J. The batten now comes forward to beat up the thread, and as it advances the lever ll strikes the tongue I, whereby the lever ll will be raised and turn the shaft a and thus swing the fork G down into about the position shown inv Fig. 10, thereby drawing the thread (0 across the face of the fork J and conlining it between said fork and the fork G, as in Fig. 6. As the batten new advances slightly farther the fork G, by pressing the thread a against the fork J, will carry said fork J backward, thereby moving the lower end of the rod 71, outward, which carries with it the lever L, thereby moving the free end of said lever from over the free end of the lever M and from beneath the stop U. During the above operations the shaft Q is revolving, and just as the batten comes forward to beat up the thread the part .9 of the cam P reaches the lever O and raises it slightly, thereby also raising the free ends of the lovers M L slightly. \Vhen the lever L is now moved outward from the lever M, as stated, it will slip off the end of the lever M, and as said lever M was raised slightly, as stated, the free end of the lever L will be prevented from again coming over the top of the lever M until said lever has been depressed again. As the batten comes forward, as above stated, it also ongages the upper end of the lever R, thereby moving the lower end of said lever from over its lever M but as the narrow part of the cam P is inv contact with the lever O at this time the lever M is not moved by the cam P lvery time the batten comes forward it will move the lever R. \Vhile the batten is now returning to its outward position the projection t of the cam P will engage the lever 0 and raise said lever to its fullest extent, thereby raising the free end of thelever M, which is permitted by the lever L being away from. the stop U. \Vhen the batten reaches its outward position, the shuttle will be thrown again from the right to the left. As the batten new again advances to beat up the thread it will engage the lever R and move the lower end of said lever outward from over the lever M but just before the end of said lever isthus moved outwardly the part .9 of the cam P engages the lever O to slightly raise said latter lever, and with it the levers M and It, so that as the lever R is moved from the lever M by the batten, as stated, it will be depressed by the spring q and will be prevented from coming over the lever M by said lever being in its way. As the shaft Q still rotates the projection on the cam P will raise the lever 0 and thereby the lever M to its fullest extent. The batten now having moved outwardly again, the shuttle is thrown back, as before, to cross the path of the forks G J. Each time the batten comes forward and the shuttle is on the right-hand side of the batten its thread will engage the fork J to move the lever L outward to permit the free motion of the lever M, while when the shuttle is at the left of the batten the lever B will be moved outward to permit free movement of the lever M the cams P P alternately moving the levers 0 0 one for each stroke of the batten. If, new, the shuttle is thrown to the right, but for some reason the thread does not cross the face of the fork J to be pushed against said fork by the fork Gfor instance, if the shuttle sticks in the shed, or if the thread breaks, or the cop becomes empty, so that no thread will be drawn across in front of the fork J the lever L will be left over the lever M, because there is now no thread to move the fork J, and as the cam P rotates andits projection 25 engages the lever O and raises said lever to its fullest extent the inner end of the lever M, being held down by the lever L and stop U, will cause the free or outer end of the lever M, that is beneath the rod N, to be raised by the .rod '1", whereby instantly the rod N will be thrown to disengage the actuating mechanism, and thereby the loom be stopped. The mechanism shown in my former patent, No. 308,359, November 25, 1884, may be used for stopping the loom upon the disengagement of rod N. If, on the other hand, the shuttle be thrown toward the left and it should stick in the shed and prevent the forward motion of the batten, the lever B, by not being moved away from the end of the lever M will prevent the raising of said end of said lever M by the cam P and thereby the opposite end of said lever will be raised by the cam I when its projection t engages the lever 0 thereby raising the rod N through the lever M which immediately acts to disengagethe actuating mechanism of the loom. The batten may be actuated by hand by the means shown in United States Patent No. 286,081, dated October 2, 1883, or otherwise.

From the above construction it will be seen that the forks G J and the lever R act alternately to disengage the actuating mechanism-that is to say, if the shuttle should have arrived with its thread at the right or at the side of the loom at which the fork J is situated the forks G J, with the thread a will act to move the lever L away from the lever M and permit free movement of the latter lever; but if said thread does not come between said forks the lever L will remain between the lever M and stop U, and thereby the cam P will be permitted,through the levers O M, to stop the actuating devices; also, that if the shuttle should be thrown to the left, or at the side opposite the forks G J, and should stick in the shed and prevent the forward swing of thebatten, the lever R will remain over its lever M so that the cam P will act to throw the rod N to stop-the actuating mechanism of the loom. 7
